nginx 监听多个端口 80和81

首先找到nginx的配置文件nginx.conf，打开配置文件后找到类似下面一段：

[root@localhost nginx]# cd /etc/nginx/conf.d/

然后把目录下面的文件都列出来：

[root@localhost conf.d]# ll  

默认的话，目录下面有个default.conf文件

打开default.conf文件后如下：

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    access_log  /var/log/nginx/access.log  main;

    root        /var/www/baidu;
    index       index.php index.html index.htm;
    location / {
        try_files $uri $uri/ =404;
    }

    error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php($|/) {
        try_files $uri =404;
        #rewrite ^/index.php/(.*)$  /$1 last;
        fastcgi_pass unix:/var/www/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;

        fastcgi_intercept_errors on;
        fastcgi_ignore_client_abort off;
        fastcgi_connect_timeout 60;
        fastcgi_send_timeout 180;
        fastcgi_read_timeout 180;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_temp_file_write_size 256k;
    }
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

如果把上面的配置作为本地配置一个百度网站的设置，那么其访问的端口为默认80端口，访问地址就是：http://localhost/

如果我们想用81端口配置为本地的另外一个网站的访问入口，应该怎么配置呢？

首先你需要在conf.d目录下创建一个以.conf结尾的文件，比如：google.com.conf文件，或者直接copy一个default.conf文件也可以，具体配置如下：

server {
    listen       81;
    server_name  localhost;

    #charset koi8-r;
    access_log  /var/log/nginx/access.log  main;

    root        /var/www/google;
    index       index.php index.html index.htm;
    location / {
        try_files $uri $uri/ =404;
    }

    error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php($|/) {
        try_files $uri =404;
        #rewrite ^/index.php/(.*)$  /$1 last;
        fastcgi_pass unix:/var/www/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;

        fastcgi_intercept_errors on;
        fastcgi_ignore_client_abort off;
        fastcgi_connect_timeout 60;
        fastcgi_send_timeout 180;
        fastcgi_read_timeout 180;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_temp_file_write_size 256k;
    }
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

保存后，重启nginx服务器

访问：http://localhost:81看看是否成功吧。

注意：配置里面的目录文件一定要存在，不然无法启动nginx。
